I highly doubt we will see her death. It is in fact a kids and they already borderline with some scenes. For example them having take off some of Ventress's executions. They most likely will continue it in a novel or comic.
EDIT: I fixed my mistake...
I understand that it's a kids show. I'm not saying that the death should be graphic or anything like that. But I am saying that it would further the Prequels purpose and explain certain things about Anakin's demeanor.
This is just my opinion. While my logic is sound, I don't see her death happening. Don't want to damage the feelings of those poor kids.
